A tomato variety named Angela, previously described, incorporates resistance to local strains of the potato virus Y group that occur in tomato plantings in São Paulo. This variety is well accepted by tomato growers and is being used as a basis for incorporation of other types of virus disease resistance. Derivatives incorporating resistance to potato Y and tobacco mosaic viruses were obtained from crosses between Ângela and T 15-1-6-1, a tomato type that is highly resistant to tobacco mosaic virus, by inoculation and selection of advance generations of the hybrid or by backcrossing, combined with selfing. The newly selected tomato types are homozygous for the recessive gene rt that controls resistance to potato Y virus and for Tm-2a that conditions tobacco mosaic virus resistance. Their commercial qualities are similar to those of the Ângela parent plant. The new tomato types, resistant to TMV and potato virus Y, are still being tested in a large scale before being released, but it is expected that they will reduce considerably the losses caused by infection with either of the two viruses, avoid injury from the synergistic effect of virus combinations in the same plant, eliminate internal browning, and seed transmission of TMV. | Derivados de tomateiro, que incorporam resistência ao vírus de mosaico Y (PVY) e mosaico comum (TMV), foram obtidos do cruzamento entre a var. Ângela, resistente às estirpes locais do vírus de mosaico Y, e T 15-1-6-1, que é altamente resistente às estirpes locais do TMV, por meio de inoculação com dois vírus, retrocruzamentos para Ângela e seleção de gerações avançadas do híbrido. Tipos selecionados do tomateiro são homozigotos para os gens Tm-2ªe rt. Suas características comerciais são semelhantes às da var. Ângela. Espera-se que os novos tipos de tomateiro reduzam perdas causadas pela infecção com PVY e/ou TMV, evitem efeitos sinérgicos entre dois vírus em combinação, eliminem a infecção do tipo "internal browning" e também transmissão do TMV pelas sementes.
